Description

Technical Field

[0001] This utility model relates to the field of fluid fuel equipment, specifically to an adjustable flame burner. Background Technology

[0002] Burners are widely used in industrial equipment to provide heat, especially in high-temperature applications, where there are specific requirements for the burner's fuel delivery capacity and flame adjustability. Existing burners typically only support one type of fuel. When the burner needs to simultaneously burn both natural gas and fuel oil, it is clearly inadequate to achieve this. To address this issue, existing patents disclose a burner capable of simultaneously using two fuels, such as Chinese Patent Publication No. CN1831430A, entitled "Burner for Mixing High and Low Pressure Natural Gas and Fuel Oil." This patent specifically discloses an injection gun, a mixing chamber, a gas nozzle, and an air distribution box. The injection gun has a nozzle at its front end, a mixing chamber between the nozzle and the gun body, and a steam channel at the center of the gun body. From the inside out, the gun body has a fuel oil channel, a high-pressure gas channel, and a low-pressure gas channel. The steam channel and fuel oil channel communicate with the mixing chamber and the nozzle. The outlet of the low-pressure gas channel is located in front of the gas gun's air intake. The air distribution box has three ventilation ducts, each equipped with a ventilation baffle. The rear baffle of the air distribution box is located behind the gas gun's air intake. While this patent supports two fuels, the design makes flame adjustment difficult, thus limiting its practical application.
